Where does the center of gravity lie, when a boy is doing sit-ups? Does weight vector pass through the base or move away from the base? Explain. |

Answer» When a BOY is doing sit-ups, the center of GRAVITY KEEPS moving up and down. Thus the centre of gravity is not fixed while doing sit-ups. It keeps changing as the boy stands up or sits down.The weight vector passes through the BASE but it also keeps moving slightly.Hope this answer is HELPFUL to you. Thank you. |
